Question WebGL + GRPC does not work after build

Hey guys,
I wrote a GrpcService Class:

Code (CSharp):

1. using System.Net.Http;
2. using System.Threading.Tasks;
3. using Grpc.Core;
4. using Nimbus.Core.Grpc;
5. using Nimbus.Core.Grpc.WebApi;
6. using Grpc.Net.Client;
7. using Grpc.Net.Client.Web;
8. using FileContentResponse;
9.  
10. public class GrpcService
11. {
12.     private readonly GrpcChannel _channel;
13.     private const string PRODUCTION_SERVER_URL = "https://api.xxxxxx.com";
14.  
15.     public GrpcService(string token)
16.     {
17.         _channel = CreateAuthenticatedChannel(PRODUCTION_SERVER_URL, token);
18.     }
19.  
20.     private GrpcChannel CreateAuthenticatedChannel(string address, string token)
21.     {
22.         var credentials = CallCredentials.FromInterceptor((_, metadata) =>
23.         {
24.             if (!string.IsNullOrEmpty(token))
25.             {
26.                 metadata.Add("Authorization", $"Bearer {token}");
27.             }
28.             return Task.CompletedTask;
29.         });
30.      
31.         var channel = GrpcChannel.ForAddress(address, new GrpcChannelOptions
32.         {
33.             HttpHandler = new GrpcWebHandler(new HttpClientHandler()),
34.             Credentials = ChannelCredentials.Create(new SslCredentials(), credentials),
35.             MaxReceiveMessageSize = 1024 * 1024 * 50, // Set the maximum message size to 50 MB
36.             MaxSendMessageSize = 1024 * 1024 * 50 // Set the maximum message size to 50 MB
37.         });
38.      
39.         return channel;
40.     }
41.  
42.     public FileContentResponse GetFileContentById(string id)
43.     {
44.         id = RemoveFilesSubstring(id);
45.         var _filesServiceClient = new FilesService.FilesServiceClient(_channel);
46.         var request = new IdRequest
47.         {
48.             Id = id
49.         };
50.  
51.         return _filesServiceClient.GetFileContentById(request);
52.     }
53.  
54.     private string RemoveFilesSubstring(string input)
55.     {
56.         int index = input.IndexOf("/files/");
57.         return index >= 0 ? input.Substring(index + "/files/".Length) : input;
58.     }
59.  
60.     private void OnDisable() {
61.         _channel.ShutdownAsync().Wait();
62.     }
63. }

I have successfully get response from my server using this class at the Editor level, but when I build I get the following error:

Code (CSharp):

1. Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. DllNotFoundException: Unable to load DLL 'libc'. Tried the load the following dynamic libraries: ", DebugException="System.DllNotFoundException: Unable to load DLL 'libc'. Tried the load the following dynamic libraries:
2. ")

I could not find any information or documentation regarding GRPC and WebGL...
Any Ideas?
